Bigelow LLC Research
Advisory Approach
Bigelow LLC is an independently owned M&A advisory boutique established in 1935 with a singular and passionate client focus: Entrepreneur Owner-Managers (EOMs). The firm operates with a distinctive thesis-driven approach to M&A advisory: they believe that the most successful outcomes for entrepreneur owner-managers come from deep understanding of their unique values, legacy concerns, and personal goals—combined with institutional-quality M&A process execution. Their sweet spot is founder-owned and owner-managed businesses valued between $30 million and $400+ million, where the owner's involvement and vision are central to the company's identity and success. Unlike virtually all competing advisory firms, Bigelow is independently owned with only one source of revenue: their EOM clients. This creates complete alignment—no referral fees, no products to sell, no investing, trading, lending, or underwriting side businesses. No conflicts. Just pure focus on achieving their clients' potential.
Sector Focus
Bigelow's transaction history demonstrates broad cross-industry experience with particular depth in manufacturing and industrial services. Analysis of their deal portfolio reveals consistent expertise across multiple sectors:
Manufacturing & Industrial: Bigelow has extensive experience advising specialty manufacturers, precision machining companies, and component manufacturers serving aerospace, defense, automotive, and industrial end markets. Notable examples include Fowler High Precision (dimensional metrology and calibration services), Welch Fluorocarbon (thermoformed plastic components), Boston Centerless (precision cylindrical grinding), and Bren-Tronics (portable power systems for defense). These deals demonstrate deep understanding of plant-level economics, operational complexity, and buyer networks in industrial manufacturing.
Healthcare Services & Pharmaceutical: Bigelow maintains active practices in healthcare services and life sciences, with demonstrated expertise in regulatory affairs consulting, behavioral health platforms, and professional services firms serving healthcare. Opus Regulatory (pharmaceutical regulatory consulting, recapitalized with Audax Private Equity) and Boothby Therapy Services (behavioral health platform) exemplify their healthcare sector capability.
Business Services & Specialty Manufacturing: The firm has also closed transactions in HVAC contracting, plumbing services, and specialized manufacturing. Accutemp Engineering (HVAC installation and service provider) and California Faucets (luxury decorative faucet manufacturer) demonstrate breadth in service-oriented businesses and niche manufacturing.

Bigelow has facilitated buy-side and sell-side transactions, recapitalizations, and strategic partnerships.
Process & Fee Structure
Bigelow operates with an institutional, thesis-driven approach to sell-side M&A processes. While specific fee details are not publicly disclosed, they employ a traditional M&A advisory fee structure typical of lower-middle-market boutiques: retainer fees (monthly advisory fees) credited against success fees. Based on industry norms for independent boutiques of their scale and deal size, typical arrangements likely include retainers in the $10,000-$30,000 monthly range credited against success fees calculated using modified Lehman or flat percentage methodologies. Their process is rigorously designed to maximize buyer outreach, quality, and cultural alignment—not just valuation. They emphasize that the right fit of values, culture, and alignment by best investors unlocks superior enterprise value.
Buyer Network
Bigelow maintains strong relationships with a diverse network of buyers: private equity firms (Audax Private Equity, Pfingsten Partners, Genstar, May River Capital, Avesi Partners), strategic acquirers across industrial sectors (EnerSys, American Bath Group, UFP Technologies), and family offices. Their deal history shows particular strength with middle market PE firms and operationally-oriented buyers who value management continuity and cultural preservation—aligning with their EOM client focus. Their transaction activity demonstrates consistent access to quality buyers across manufacturing, healthcare services, business services, and specialty industrial sectors.
Competitive Positioning
Bigelow differentiates through:
-
EOM Specialization & Alignment: Unlike generalist banks serving everyone, Bigelow focuses exclusively on Entrepreneur Owner-Managers. Their team understands the unique psychological, financial, and legacy concerns of founders and owner-operators. This singular focus creates genuine alignment.
-
Independence: As an independently owned firm with no other revenue sources (no investing, trading, lending, or product sales), Bigelow eliminates conflicts of interest that plague larger, diversified advisory firms.
-
Institutional Process + Human Understanding: They combine institutional-quality M&A execution (data rooms, buyer management, process rigor) with deep empathy for the EOM experience. They view their work as a "calling," not a transaction factory.
-
Thought Leadership & Education: Bigelow invests significantly in educating EOMs through their "Positive Enterprise Value" blog, podcasts, annual Bigelow Forum (16 years running), and published research on behavioral finance and positive psychology—helping owners prepare psychologically for capital gains events.
-
Long-Term Relationships: Bigelow frequently works with clients for years in advance of a transaction, building deep understanding of their business, values, and goals. This results in better matches and superior outcomes.
Not a Fit If
Bigelow will typically decline engagements where:
- Owners want a limited or rushed process
- The business model is pure financial engineering (asset plays vs. going concerns)
- Significant pending litigation or regulatory issues exist
- Owners prioritize speed/valuation over cultural fit and values alignment
- The firm is a subsidiary or owned by PE/corporate owners (they serve EOMs, not portfolio companies)
Team
Bigelow operates as a scrappy, collaborative boutique with 26 employees. The team includes individuals with deep M&A experience, former operators, and advisors with special expertise in specific industries. Key leadership includes:
- Pete Worrell, Co-CEO: Extensive M&A experience, author, speaker on positive psychology and EOM topics.
- Rob MacLeod, Co-CEO: FINRA-registered managing director with 25+ years in M&A advisory, deep experience in operational advisory and process management.
- Christopher Fincke: Associate with background in corporate advisory and business consulting.
The team also includes advisory professionals with backgrounds in specific sectors (healthcare, manufacturing, industrial services). Team members regularly present at industry conferences and contribute to the firm's thought leadership publications.
